There will probably be a lot more tutorials down the road. UE4 was released just over a month ago, it’s still very new and everyone is figuring out how to use it, currently. And I can only repeat what I already suggested in the last thread (that I linked above):
If you already ‘know’ C++, then a good way to get started might be to just read the code of some of the available projects. Create a new project from the C++ FPS template for instance and read the implementation of the character, game and projectile classes. This is what I did and it really helped getting started.
You can read the engine source or documentation all you want, but if you don’t know what you’re looking for you’ll be sitting there for a long time. But once you get a feeling for the architecture, how UObject, UWorld, UActorComponent, USceneComponenet or AActor relate to one another, it will become easier to find the relevant part of the engine source or documentation that you’re looking for.
You can also start reading the codes of the templates or any of the C++ projects from the Marketplace. I think the Shooter Game is C++.
